You're absolutely right Jim. Many times it's called braze welding.
Unfortunately when you tell someone they will "weld" something they're not
going to look any farther because they think of sparks, arcs and something
they can't do. Fortunately you can braze even copper to copper with simple
materials available at the local Home Depot.

And that's an excellent choice if it's available :)
